FLOUR BOLTING AND DRESSING MACHINE.

SPECTFICATION forming part of Letters Patent No. 302,165, dated July1834' Application filed July 14, 1882: (No model.) Patented in EnglandJuly 31, 1882, No. 3,635, and in Germany October 29, 1882,

1'0 aZZ whom it may concern:

Be it known that I, HEINRICH SEcK, of Frankforton-theMain, Germany, inthe Province of Hesse-Nassau and Kingdom of Prussia,

5 have invented certain new and useful Iniprovements in Flour Boltingand Dressing Machines, of. which the following is a specification.

This invention relates to improved means of fastening or applying thebolting or screening cloth or silk to flour-bolting and dressingmachines, and to certain other features of construction, all ashereinafter more fully describedand claimed.

My invention is shown in the accompanying drawings, and in thesedrawings- Figure 1 is a partial longitudinal section of my improvedmeans for securing the cloth. Fig. 2 is a transverse section through thebolting-cylinder on the line 0c 00, Fig. 1, looking toward one of theheads of the same,and showing the supporting-ribs, and in section thebearing U-arms carrying U-shaped iron bars provided with wooden barsforming the contact-surfaces for the screening-cloth. Fig. 3 is amodified form of my improvement. Fig. 4 is a sectional view on the lineyy of Fig. 3. Figs. 5 and 6 are modified forms of the fastening-barsholding the screening-cloth. Fig. 7 is a sectional view of parts of abolting-machine provided with my improvements. Fig.8 is a longitudinalvertical section of such machine. Fig. 9 is a sectional view of part ofthe opposite end of the machine, and Figs. 10 and 11 are detail views ofthe discharging-elevator at the tail of the reel.

Referring first to Figs. 1, 2, 7, and 8 of the drawings, a and b are theheads of the bolting-cylinder A, to which heads are fixed near theirinner periphery a suitable number of projecting U-arms, 0, havingsupporting-ribs 0. Every two opposite arms 0 carry a U- bar, (I, made ofcast-iron or other suitable material, said U-bars (l fitting snugly theU -arms 0 and extending across the entire length of the cylinder A.

e and f are screw-bolts, provided with nuts for holding the U-bars d inposition in the U- arms 0 and fastening said bars to the heads a I). Tothis end the bolt of the screw 6 is made,

near its inner end, of a rectangular or square form, fitting snugly theend of the U-bar, and this rectangular end of the screw-bolt eisprovided with ahole for the screw-bolt f to pass through, the end of thelatter carrying a nut which holds the screw-bolt e, the U -bar d, andthe U-arm cin a tight connection. The screwbolt 6 is provided at itsouter end with a similar nut to prevent the lengthwise movement of theU-bars (I. Now, each U-bar is fitted up with a snugly-fitting wood bar,9, extend ing from one head to the other, and the outer surface of saidwood bars 51 is rounded off, and is provided with a suitable covering,over which the screening-cloth is drawn. In the drawings the screeningor bolting cloth is illdicated by dotted lines z, and the said cloth isprovided with a strong edge, made of linen or other suitable material,the rim of which is folded over a rope, -Z, and is fastened by means ofstitching to the upper side of the said linen edge again, thus inclosingthe said rope Z and forming a swelled edge on the screening-cloth.

h h are bars, made of iron or other conven- 7 5 ient material,which arebent in such a form as to form, when screwed upon the heads a b, a spacesimilar to that formed bya tube or pipe slotted lengthwise. The rope Z,inclosed and held by the linen edge of the bolting-cloth, is insertedinto this said space, so that when the bolti n gcloth is stretched theed ge,with the rope Z,will be pressed against the inside of the slot,between the lower edge of the bar it and the upper surface of the woodbars ,9, thereby 8 5 holding the bolting-cloth in a stretched position.

There may be applied one bar h between each two adjacent U-bars d; orthe bar h may consists of one single ring screwed to the heads neartheir inner periphery,above the said bars d. V In the former instancethe bolting-cloth will have a polygonal form,while in the latter case itwill be cylindrical. When there isbut one ring used,the latter must beso constructed as to allow of a short piece of it being taken out forinserting the end of the rope Z of the bolting-cloth. When there areseveral bars h applied, it will be necessary only to unscrew one of themto insert the rope Zinto the space IOO formed by the one adjacent barand the wood bar and to slide the rope forward until it issues from theother adjacent bar it, when it may be tied together, and the unscrewedbar h may be screwed on again to cover the connected part of the rope Z,as will be easily understood. The cloth is then stretched in the usualway.

In the modification shown in Figs. 3 and 4 of the drawings the bars ithave been replaced by the ring 7:, an annular projection, m, beingapplied to the heads below the said ring 7t to form the slotted tube,serving for the reception of the rope Z to hold the stretched cloth.Some other forms of such slotted tube are shown in Figs. 5 and (5. Inorder to insert the rope I or the swelled edge of the boltingcloth intothe space formed by the ring 70 and the projection m, (shown in Fi 3ofthe drawings,) it is necessary only to unscrew the part i of the saidring L, as shown in Fig. 4, and to slide the rope or swelled edgeforward in the same manner as has been described with reference to Figs.1 and 2 of the drawings. The said annular projection m is of coursebroken or intersected by the U-arms c.

I wish it understood that I do not confine myself to the exactconstruction and arrangement of devices for holding the swelled orpuffed up edge of the bolting-cloth when stretched as many modificationswould suggest themselves to the skilled mechanic without departing fromthe spirit of my invention.

Another part of my invention relates to the coinbinatiomwith a flourbolting and dressing machine, of an improved elevator, the same beingmounted in the same height and on the same axis with thebolting-cylinder. This part is shown in Figs. 9, 10, and 11 of thedrawings. The said elevator is fixed to the head I) of thebolting-cylinder A,and rotates with the same, its rotary motion beingabout one-tenth (more or less) of the speed ofthe beater-wheel withinthe said cylinder A. The grist in the latter is moved from thelel't tothe right by means of the heaters until it enters the elevator 13through the openings on, said elevator rotating within a stationary box,0', and being provided with a number of scoops, a. The said box 0 has aspout, 0. The scoops a are closed by a ring, They will elevate the gristand throw the samethrough the spout 0 into the grinding-rollers. It willbe seen that by this arrangement the construction of the machine isrendered 'far more simple, and that it p claim as new, and desire tosecure by Letters Patent, is

1. In bolting-machines,the combination,with the bolting-cloth, of themetal U-bars (1, extending the length of the bolting-cylinder, and thewooden bars g, for filling the. grooves of said metal bars d,substantially as described.

2. The combination of metal U-shaped bars d, U-shaped brackets c, theheads a b, the wooden filling-bars g, and the boltiug-eloth,substantially as described.

8. In a bolting-reel, the combination of the reel-heads, a continuousbolting-cloth provided at its opposite ends with swelled edges, by whichit is stretched and held in place, and an annular bracket or keepersecured to each reel-head, substantiallyas described.

4-. In a bolting-reel, the reel-heads, a con tinuous bolting-clothsecured thereto and pro vided at its opposite ends with swelled edges,by which it is stretched and held in place in each reel-head, as hereindescribed, with the longitudinal U-shaped bars containing woodenfilling-bars, substantially as described.

5. In a bolting-machine, the combination of the reel, the elevators a,made in one piece with one head of the reel, the ring 1), and thestationary box 0, provided with the spout 0, substantially as described.

6. A reel-frame for flour-bolting machines, consisting, substantially,asbefore set forth, of the heads a. I), the arms a, projecting there from,the U-shaped bars (Z, having their ends seated in recesses in said arms,the bolts 0 f, and a wood filling for the grooves of the bars (I.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
